Whereas most birds are sole proprietors of their nests, some tropical species "time share" together -- a discovery that helps clear up a 150-year-old evolutionary mystery, says a biology professor. (sciencedaily.com)
We're taught today that new species generally emerge as a result of a geographic barrier such as a mountain range or river, creating two separate populations that can't easily move from one place to the other," says Dr. Friesen, an expert in evolutionary biology. (sciencedaily.com)
So, someone who believes evolutionary biology is the cat's meow, and who finds a widespread human practice, so widespread that we have never encountered a single culture where it is absent, and one into which a huge amount of energy is poured, would have to say it is most likely adaptive, right? (consultingbyrpm.com)
In biology, a substitution model , also called models of DNA sequence evolution , are Markov models that describe changes over evolutionary time. (wikipedia.org)
Third, and I think this is the most important part, the researchers did not simply observe changes in key variables over time but they developed a sophisticated model of the biology underlying the data. (scienceblogs.com)

Using computational modelling that spatial processes can create evolutionary outcomes that depart from basic population‐level notions from these standard macroevolutionary models. (palass.org)
Spatial variation interacts with evolutionary processes in ways that produce patterns of trait change that differ markedly from the expectations of standard statistical evolutionary models like Brownian motion, directional selection and adaptive peak (Ornstein-Uhlenbeck) models. (palass.org)
In this paper, I critically review the ways in which spatial processes cause departures from these standard evolutionary models. (palass.org)
Ecological and evolutionary processes historically have been assumed to operate on significantly different time scales. (datadryad.org)
We know now from theory and work in experimental and model systems that these processes can feed back on each other on mutually relevant time scales. (datadryad.org)
Over the last 20 years, Bayesian methods have reshaped phylogenetic inference and gained widespread popularity due to their high accuracy, the ability to quantify the uncertainty of inferences and the possibility of accommodating multiple aspects of evolutionary processes in the models that are. (researchgate.net)
Such features indicate to the investigators that these sequence elements were functional genes at one time in evolutionary history, but eventually lost function due to mutations or other biochemical processes, such as reverse transcription and DNA insertion. (reasons.org)

Stockier than us, with heavy brows and sloping foreheads, it had long been assumed that Neanderthals were primitive and animalistic: subhuman. (cam.ac.uk)
Every time I see a new report about yet one more very humanlike feature of Neanderthals, I'm reminded that the Bible 's history is true and evolutionary ideas are wrong. (answersingenesis.org)
You see, when the bones of Neanderthals were first discovered, they were assumed to be our evolutionary relatives, but not fully human. (answersingenesis.org)
So next time you see something that appears to contradict the history in God 's Word, remember Neanderthals and the avalanche of evidence that did not confirm evolutionary expectations but confirms the Bible 's history. (answersingenesis.org)

Our findings confirm predictions that eco-evolutionary feedbacks occur in natural populations. (datadryad.org)
We have designed and analysed an eco-evolutionary and functional-trait-based model of three interacting trophic levels and we have simulated adaptation and diversification in traits as a response to eco-evolutionary feedbacks. (lu.se)

And, of course, the more widespread the trait is, the more we should suspect it is adaptive: it might pop up in one individual or a small group as a fluke that will disappear soon, but if we find that trait surviving in many, many groups across long stretches of time, the odds greatly increase that it confers some advantage. (consultingbyrpm.com)
To see how, at times, it might be adaptive to believe a falsehood, let us consider an animal that needs to defend its young against a large predator. (consultingbyrpm.com)
The planetary transit was also validated to occur on the assumed host star through adaptive imaging and statistical analysis. (lu.se)
Rather than operating as genuinely adaptive phenomena associated with evolutionary advantage, we suggest that belief systems emerge as a by-product of evolutionary pressures. (bvsalud.org)

Estimates of evolutionary distances (numbers of substitutions that have occurred since a pair of sequences diverged from a common ancestor) are typically calculated using substitution models (evolutionary distances are used input for distance methods such as neighbor joining ). (wikipedia.org)
It is also necessary to assume a substitution model to estimate evolutionary distances for pairs of sequences (distances are the number of substitutions that have occurred since sequences had a common ancestor). (wikipedia.org)

1 However, this age was entirely dependent on tying the molecular data to the evolutionary timeline presumed to exist in the related fossil data-an example of circular reasoning that actually proves nothing. (icr.org)
In the case of a recent report, evolutionists look to chance and "molecular time travel" (as the article calls it) rather than the Creator as the explanation for their theory. (icr.org)
It is rather an exceedingly flimsy, unconvincing story of a major evolutionary extrapolation via '"molecular time travel" using ancestral protein reconstruction. (icr.org)

In their study published in Science , the researchers correlated the evolutionary time of "divergence" for SloEFV (i.e., the time when it supposedly split off from its ancestor virus) with the assumed evolutionary date of divergence of its sloth host, along with several other hand-picked mammals, citing this correlation as evidence that the SloEFV evolved at least "39 million years" ago. (icr.org)
Now researchers have described at least a dozen different species that live underwater for several weeks at a time. (latimes.com)
Once a DNA sequence is labeled a pseudogene, bias sets in and researchers just assume that it lacks function-not because it has been experimentally demonstrated to be nonfunctional, but because of the stereotyping that arises out of the evolutionary paradigm. (reasons.org)
Last year I spent time with researchers at the Yale Program on Climate Change Communication , which has conducted countless scientific studies on public opinion and behaviour around climate change. (abc.net.au)

Statistical model fitting is now commonly used to estimate which kind of evolutionary process best explains patterns of change through time using models like Brownian motion, stabilizing selection (Ornstein-Uhlenbeck) and directional selection on traits measured from stratigraphic sequences or on phylogenetic trees. (palass.org)
Another alternative is to use summary MSC methods like ASTRAL, but such methods are also unsatisfactory because they infer branch lengths in coalescent units, and so cannot estimate divergence times. (biorxiv.org)

To enable fuller use of available data and more accurate inference of species tree topologies, divergence times, and substitution rates, we have developed a new version of *BEAST called StarBEAST2. (biorxiv.org)

Evolutionary losers ultimately rendered extinct by their own deficiencies. (cam.ac.uk)

They also learned that the seasonal species had not bred with each other for periods ranging from around 1,000 to 180,000 years, providing a series of "time shots" of divergence, Dr. Friesen explains. (sciencedaily.com)
However, even if the time of divergence is accepted as accurate, for the sake of argument, it leads to a disturbing conclusion. (icr.org)
This is an inconsistent estimator of species tree topology, and a worse estimator of divergence times. (biorxiv.org)

They espouse that evolution explains why gene sequences like SloEFV change rapidly over time, as well as why SloEFV in particular has changed hardly at all. (icr.org)
